SIGHT-FEED.

Specification of Letters Patent.

Patented J an. 11, 1910.

Application tiled April 17, 1908. Serial No. 427,619.

To all whom it 'may concern.'

Be it known that I, JOHN C. HILL, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Sight-Feeds, of which the following is a specification.

This invention relates to that type of feed indicators for multipledischarge lubricators, in which means under the control of the operatorcan be brought into action to visibly indicate the floiv of thelubricant through any particular discharge; and the present improvementhas for its object. to provide a simple and eiiicient structuralarrangement and combination of parts Whereby the discharge from any oneof the series of discharges can be brought to a general sight feed tubeor vievi7 passage to give an indication of its flow, when required bythe operator, all as will hereinafter more fully appear.

In the accompanying drawings :gliigure 1. is a longitudinal section online Fig. l, the series of outlet passages in vfront of the plano onwhich the section is taken being shown in dotted lines. Fig. Q, is adetail plan view. Fig. 3, is a transverse section on line.'-m Fig. 1.

Similar numerals of reference indicate like parts in the differentviews.

Referring to the drawings, 1 represents the main trunk or housing, which,may be the cover portion of a lubricator casing as shown. .As in myformer patented construction No. 853,695 of May 14, 1907, such heus ingis formed -ivith a series of vertical passages 2, the upper portions ofwhich form the seats for the series of controlling piston valves,hereinafter described.

3, are a series ol inlet tubes or passages, connecting the multipledischarges of the pumping mechanism with the lower end of the passages 2aforesaid.

4, are a seriesl of outlet tubes or passages connecting with theaforesaid passages Qi. midway the height of the saine, and aapted toconduct the lubricant to the different points of use.

5, are a series of tubular piston valves.

sliding in the upper portions of the vertical Y passages Q, and eachformed With a pair o'f portati and 7 in vertical separated relation.Each of said valves in its upper and normal position as shown in Fig. 3,is adapted to register a passage 2, through a lower port t3, with anoutlet passage 4, to cause a direct flow of lubricant to the point ofuse. ln its other and down position such valve is adapted to register apassage 2, through an upper port 7, with an individual. branch of acommon passage hereinafter described, at the same time closing thecommunication between the aforesaid lower port G and the outlet passage4.

8, are a series of springs arranged beneath the tubular piston valves 5,with a tendency to maintain said valves in the upper position above setforth.

9, are a series of stems attached to the upper ends of the piston valves5, and passing through guide bushings 10 screwed into the upper ends ofthe series of vertical passages 2, aforesaid.

11, are a series of handles or buttons earried on the upper ends of thestems 9 aforesaid, and affording a convenient means for the manualdepression of any individual valve, when desired.

12, is a transverse passage formed in the housing 1 and havingindividual ports or brain-hes 1? connecting with the vertical pas sagesand adapted to register with the npper ports 7 of the valves 5 When thesaine are depressed in the manner above set forth.

14, are individual notches formed in opposed relation in the peripheriesof pairs of the handles or buttons 11 and adapted to form guide groovestherefor having sliding engagement with stationary vertical guide pins15 on the casing or housing 1, to prevent a turning movement of saidhandhI and attached piston valves and in consequence maintain theports't and 7 of the valves in proper line with the ports 4 and 13 ofthe casing, during'the continued use of the apparatus.

16, is a vertical passage formed in the casing 1, with its side Wallmade transparent in any usual manner, preferably by means of a tube ofglass 1T secured in top and bottom seats by a holding gland 18 sercvvedinto the upper part of said passage as shown. Attop lthe passage 16 isin communication with the transverse passage 12, at a point above thegland 18, and at bottom is in communication with the interior of thelubricator casing, so that the lubricant passing through the passage 16will be returned to said casing. 19, is a screw ca closing the upper endof the passage 16 aforesaid.

Q0, is a Central depending nipple or funnel shape partition which ispreferably formed as an integral part ot' the gland 1S, and. adapted loeolleet` the lubricant coming through the passage l2 and discharge thesame centrally down through the view tube 1T aforesaid.

2l, is a vertical vent pipe attached to the gland i8 and adapted to aidin the free tion' ot' the lubricant through the nipple 20, by thepassage` ot' the air in the view tube from a point'y heloiv to a pointabove said gland.

l ith the present Construction, any7 partieular discharge can be made t0give a visible indication of its tlovv, by a manual depression ot' itshandle or button l, to eanse a tlow ot' the luhrieant through the singleview tuhe eommon to the whole series ot' disY eharges. With the normalor raised condition ot said handles the flow of the luln'ieant is direetand without visible indication.

llaving thus t'ully described my said invention what I elaim as new anddesire to secure liv Letters latent, is.:-A
